//touch的响应方法
-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
CGPointpoint = [[touches anyObject] locationInView:self.view];//convert point to the white layer's coordinates拿到在self.view上但同时在whiteView上的点，下面的同这里一样，不一一解释了
point = [whiteView.layerconvertPoint:point fromLayer:self.view.layer];
//get layer using containsPoint:
if([whiteView.layercontainsPoint:point]) {
//convert point to blueLayer’s coordinates
point = [blueLayer convertPoint:point fromLayer:whiteView.layer];
if([blueLayer containsPoint:point])
{
[[[UIAlertView alloc] initWithTitle:@"Inside Blue Layer"message:nildelegate:nilcancelButtonTitle:@"OK"otherButtonTitles:nil] show];
}else{
[[[UIAlertView alloc] initWithTitle:@"Inside White Layer"message:nildelegate:nilcancelButtonTitle:@"OK"otherButtonTitles:nil]show];
}
}
//－－－－－－－－－－华丽丽的分割线，从这里开始是我写的点击的方法，相对来说比上面使用起来更方便点// CGPoint point=[[touches anyObject]locationInView:self.view];// CALayer *layer=[whiteView.layer hitTest:point];// if (layer==whiteView.layer) {// UIAlertView *alertView=[[UIAlertView alloc]initWithTitle:@"" message:@"Inside white layer" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles: nil];// [alertView show];// }// else if (layer==blueLayer){// UIAlertView *alertView=[[UIAlertView alloc]initWithTitle:@"" message:@"Inside blue layer" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles: nil];// [alertView show];// }}
